How to debug Changhong smart dual mode high-definition digital satellite TV receiver
The manual modification steps by remote control program, the TV screen pop-up program list, and then move the cursor to the need to modify the program, edit the PID menu, according to Huang Jian TV screen pop-up sub remote controller, will find the video PID and audio PID were modified, in press confirm key program the synchronization, press the green button to switch the satellite switching satellite, remove excess program, press the red button, button to save the data OK.Hope to be of help to you
The other one is press the menu button, pop-up menu in the TV screen, the keys to the button of the remote control system according to the program, press the confirm button, the pop-up dialog box requires a password, enter the password 9999, in accordance with the confirmation button pop-up menu, press program button of the remote control keys to restore the factory settings, press the confirm button receiver will restore factory settings, and then move the cursor to automatically search the sub menu, press the confirm button will automatically search out the program, after the program search, some of the programs and the programs menu does not need to manually modify the synchronization, synchronization to.
12, 5, 9 satellite, the satellite TV system upgrade, pot parameters adjusted, the adjusted parameters are as follows; the downlink frequency 11880, left polarized, symbol rate of 28800, there are 20 sets of TV programs. Downlink frequency of 12100, right-handed polarization, symbol rate of 28800, there are 3 sets of TV programs. Downlink frequency of 12140, right-handed polarization, symbol rate of 28800, there are 20 sets of TV programs. A total of 43 programs, 2 programs less than in the past, copycat machine can be carried out according to the above manual search frequency, search if the audio and video synchronization, can be modified respectively for the synchronization of audio and video PID can normally watch.
